Its a very complex answer. Here's the short version. Millions of years ago plants absorbed energy from the sun. Those plants got buried and time, pressure and heat turned them into fossil fuels. We clean it up, run it through our engines, where with the proper amount of pressure and temperature the fossil fuel will release the energy stored from the sun millions of years ago and create heat.
The process is called combustion. Any hydrocarbon will combust if pressurized (heated) enough. Diesel fuel self ignites when subjected to about 22 to 1 compression. Gas engines assist the initial combustion with a spark plug.

Why do modern cars burn hydrocarbon fuels in their engines?
Hydrocarbon fuels are energy dense, easily transported, relatively cheap.
Why do most modern cars burn hydrocarbon fuels in their engines?

What is made when hydrocarbon fuels burn?
Co2+h2o
Why is it usually difficult to burn different hydrocarbon fuels efficiently in the same appliance?
Because different fuels need different amounts of Oxygen and heat to ignite.
What is the cloud trail from the engines on a high flying airplane?
Basic answer is water vapour from the combustion of the hydrocarbon fuel burnt in the engine. The low temp at high altitude causes the vapour to condense - so it is a man made cloud.All hydrocarbon fuels burn in air (combining with oxygen) to produce water (hydrogen oxide) and carbon dioxide.
What harmful gas is being released when engines burn fossil fuels?
Carbon monoxide is released.
When a fossil fuels is burn energy is converted to kinetic energy?
Fossil fuels represent chemical energy, a form of potential energy. This energy was stored in the hydrocarbon molecules and can be released by oxidation (burning).
What do people burn for fuel?
People burn fossil fuels to get the energy stores in then the energy then causes the engines to run.Help to cook food.Help to light the surroundings.
What are 3 hydrocarbon fuels?
water oil
What powers cars?
Petrol, diesel and LPG are the main fuels. They are hydrocarbon fossil fuels.
What is produced when hydrocarbon fuels burn inside an engine?
Carbon dioxide and water vapour are produced when hydrocarbons are burned in plenty of air.
What do hydrocarbon reacts with when fossil fuels are burned?
Oxygen
